The present invention relates to a battery protection system for a railway vehicle. According to the present invention, provided is the battery protection system for a railway vehicle, comprising: a battery pack which is connected to a charging and discharging contactor in a railway vehicle and supplies power to a load or receives power from the outside; a battery management system which monitors the cell voltage of the battery pack and outputs a control signal for controlling the charging and discharging contactor to charge or discharge the battery pack; a comparator which monitors the pack voltage of the battery pack, compares a predetermined pack voltage charging reference value to a sensing value of the pack voltage, and outputs a comparison result; and a logical multiplication gate which operates logical multiplication of the control signal of the management system and an output signal of the comparator when the battery pack is charged or discharged and operates to protect the battery pack in accordance with an operation result.

    본 발명은 철도차량용 축전지 보호 시스템에 관한 것이다. 본 발명에 따르면, 철도차량에서 충방전 컨택터와 연결되어 부하에 전원을 공급하거나 외부로부터 전원을 공급받는 축전지 팩, 축전지 팩의 셀 전압을 모니터링하고 축전지 팩의 충전 또는 방전을 위해 충방전 컨택터를 제어하는 제어 신호를 출력하는 축전지 관리 시스템, 축전지 팩의 팩 전압을 모니터링하고 미리 설정된 팩 전압 충전 기준값과 팩 전압의 센싱값을 비교하여 비교 결과를 출력하는 비교기, 및 축전지 팩의 충전 또는 방전 시 축전지 관리 시스템의 제어 신호와 비교기의 출력 신호를 논리곱 연산하여 연산 결과에 따라 축전지 팩을 보호하도록 동작하는 논리곱 게이트를 포함하는 철도차량용 축전지 보호 시스템을 제공한다.
